it's used in filtering. When filtering you'd need something to put the filter paper on and at the same time make sure that what you're filtering goes straight into the beaker/receiver. The glass funnel allows us to do that.
Glass funnel is used for separating solids from liquids via the laboratory process of filtering
For transferring liquids from one container to another...

it is a funnel having the shape of thistle flower n a long glass stem. this funnel is used to add reagents to reaction vessels. generally made of glass

ok
They are used for vacuum filtration to separate crystals, or solids, from a liquid. Usually a neoprene adapter is used to fit the funnel to a flask that is attached to some sort of vacuum. A filter paper is used to make sure no solids get through, or clog, the funnel. Typically, it is advised, that hot solutions are not used in vacuum filtration because the reduced pressure will cause solvents to evaporate, and the solid will precipitate out; causing the funnel, and pores of the filter paper, to clog.
It is a glass funnel into which can be placed a circle of folded filter paper (so that it too is the shape of the funnel) liquids may then be poured into the funnel and while the liquids will drain through (to be collected at the base of the funnel), any solids will be retained on the paper.
Though there are exceptions, it is usually an open-top, glass funnel.
An Elmen funnel is a type of glass funnel with a wide, conical shape and a short stem. It is commonly used in laboratories for separating liquids or to transfer liquids between containers. The wide shape allows for easy pouring and minimizes spillage.
Glass funnels are used to separate solids from liquids by filtration; also they are used to pour liquids or fine powders.See many images at this link.
Well, thats an easy one... Its a funnel!
A Hirsch funnel is cylindrical and typically used for vacuum filtration of small volumes with the help of filter paper. A Buchner funnel is a flat-bottomed funnel with a porous porcelain or glass disc used for vacuum filtration of larger volumes, sometimes without the need for filter paper.
A separating funnel is a piece of equipment that is used in laboratories to separate two liquids, such as oil and water. It is mostly made of glass.
A sinterd funnel is simply a funnel with a built in filter. The filter is sintered, I think that this means that small particles are compressed together (and heated ?) to form a single piece of material with many small holes. The sintered funnels I use are made of glass, a link to some images is below (not mine). http://curlyarrow.blogspot.com/2008/01/how-to-clean-your-sintered-funnel.html I have also used sintered polyethylene and sintered stainless steel for filtering.
